Quick Question: Does the power supply fan count as a heat extractor? I can feel air being blown out of it...I think. I was thinking of adding another fan to the bottom to intake cool air and I was wondering if the power supply at the top is a heat exhaust.
Yeah, it does act as a heat extractor. Naturally, heat rises, so it's going to go in cold at the bottom and go hot out the top.
If its blowing out, yeah. Ive just checked both of my psu fans and one of them is blowing out and the other Ive found not to be working! The air in the case will be cooler than the air in the psu. I personally would add a fan taking air out the case into the psu with the original psu fan exhausting it out the back. Looks like I got beat to it, but its made me think about what you mean by bottom. I thought you meant bottom of the psu but it seems you mean bottom of the case.
Either have a look on the board for a spare supply or get a fan which uses the same supply as your hard drive and cd rom drives.
On the motherboard, there is usually a small connector socket for fans, labelled as SFAN or similar. If it is free, then you can plug the fan into that. If not then some fans have a connector which allows them to tap into the 5v rail from the power supply. (molex connector)
MOLEX, thats it. I couldnt for the life of me remember what they were called. That was bugging me since my last post.
